To-all whom it may concern.

Be it known that I, Josmu O. HAZEN, a citizen of the United States, and a resident of Haverhill, county of Essex, State of Massachusetts, administrator of the estate of MARsinuN W. HAZEN, late a citizen of the United States and resident of the city, county, and State .of New York, deceased, make application for certain new and useful Improvements in T e-Writing Machines invented by the said ifARsHMAN W. HaznN, of which the following is a full, clear, and exact description.

This invention relates more particularly to the line lock mechanism of front strike or visible 'typcwriting machines in which the carriage is adapted to be folded or shifted forward when not in use to make the machine more com act, and is a division of the application of arshman W.- Hazen, Serial 1N0. 439,967, filed June 23, 1908, now Patent No. 1,121,094, dated December 15,1914.

The primary object of the invention is to provide simple and efiicient means whereby the platen carriage may be automatically locked against movement at the end of aline and after being released may move a short distance for the purpose of adding one or more characters and the carriage again -i, automatically locked against further move-f ment. Another object of the invention is to provide sim 1e and eflicient means whereby a part of t e ke -operated mechanism may be positively loc ed and thereby revent the depression'of the key-operated evers.

A further object of the invention is to provide simple means movable with the car- I,

riage which is adapted to operate 'an ele mentor member supported on a fixed part of the machine and which when moved will 7 directly engage and positively lock it part of the feed mechanism against movement.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be omted out'in the claims at the end of the escription. I

In the drawings, Figure 1 is a fragmentary longitudina sectlon of one form oftypewriting machine embodying the invention.

Fig. 3 is a fragmcntar purtlym section, of one mechanism.

Fig. 4 is a fragmentary sectional plan of the member of the line lock mechanism which travels with the carriage, and

Fig. 5 1s atransverse section line V-V of Fig.

While the invention as shown is more particularly adapted to the form of typetaken on the writing machine disclosed in the patent granted to Frank S. Rose, No. 948,553, dated Feb. 8, 1910, in which the carriage and fold over in overhanging relation keys, and in which the type-bars'have a front strike for visible writing, it is to be platen has a vertical shift and is adapted to' to he understood that the invention is equally adapted for use in'connect-ion with other forms of typewritin'g-machines, and that the invention'is not limited to the particular construction and arrangement of the parts 2 herein shown.

The frame 10 may be of any suitable con struction and may comprise-the side plates 11 and the rear plate 12. Held to the side lates 11 transversely of the machine are one on nore supportsm on which are suspended arilnmber o key-operated levers 14, These levers are normally'forced in one direction hy'springs 15 and at their rear or inner ends ate each connected by a link 16 to a type-bar 17., Each type-bar 17 is pivotedat 18 to a bracket or support 19, and at it outer'end has head or type block 20 on which are a plurality of characters 21 indicating the; upper and lower case and figures in. the

usual way. The type blocks 20 are adapted to be moved against the platen 21 when the levers l t-are depressed for letter writing. The platen is mounted to rotate in a carriage 22. This carriage 22 moves transverselyof the machine along a bed23. The bed 23 is 'held to the bars or members 24 ofa foldable support in substantially the same manner-as disclosed in the patent referred to herein.

The universal bar 25 is locatedbyer the leversliandflthe spacing levers and is.- connected at opposite ends by l'inlts 26 to hellcrnnk levers' 27. 'lhere are two hell-crank levcrs, one'loeated at each side of the ma chine nnd snid bell-crank levers are pivoted 153M 28 and have their. arms 29 .each provided lofsides of the nlat-hine andare pivetully held to rock on. a transversely extending rod 33 located at the lon'erpnrtinn of the machine. f'lhee nrntls' 112 are connected together hv n ,trnttsvclsvl extending b'ar 33 and said her lbltogether with the arms 32 form arocking frame \vhieh is actuated each time one of the leveisll nrfth'e sna ling levers are oper'ttod.
